Table 1: Pin Description
Device Operation
The EM39LV088 uses Commands to initiate the memory operation functions. The
Commands are written to the device by asserting WE# Low while keeping CE# Low. The
address bus is latched on the falling edge of WE# or CE#, whichever occurs last. The data
bus is latched on the rising edge of WE# or CE#, whichever occurs first.
Read
The Read operation of the EM39LV088 is controlled by CE# and OE#. Both have to be Low
for the system to obtain data from the outputs. CE# is used for device selection. When CE#
is high, the chip is deselected and only standby power is consumed. OE# is the output
control and is used to gate data from the output pins. The data bus is in high impedance state
when either CE# or OE# is high. Refer to the Read Cycle Timing Diagram in Figure 1 for
further details.
Byte Program
The EM39LV088 is programmed on a byte-by-byte basis. Before programming, the sector
where the byte is located; must be erased completely. The Program operation is
accomplished in three steps:
„ The first step is a three-byte load sequence for Software Data Protection.
„ The second step is to load byte address and byte data. During the Byte Program
operation, the addresses are latched on the falling edge of either CE# or WE#, whichever
occurs last; and the data is latched on the rising edge of either CE# or WE#, whichever
occurs first.
„ The third step is the internal Program operation which is initiated after the rising edge of
the fourth WE# or CE#, whichever occurs first. The Program operation, once initiated,
will be completed within 20 µs. See Figures 2 and 3 for WE# and CE# controlled
Program operation timing diagrams respectively and Figure 12 for flowchart.
This specification is subject to change without further notice. (04.09.2004 V1.0)

Table 2: EM39LV088 Device Operation
Write Command/Command Sequence
The EM39LV088 provides two software methods to detect the completion of a Program or
Erase cycle in order to optimize the system write cycle time. The software detection includes
two status bits: Data# Polling (DQ7) and Toggle Bit (DQ6). The End-of-Write detection mode
is enabled after the rising edge of WE#, which initiates the internal Program or Erase
operation. The actual completion of the write operation is asynchronous with the system;
therefore, either a Data# Polling or Toggle Bit read may be simultaneous with the completion
of the write cycle. If this occurs, the system may possibly get an erroneous result, i.e., valid
data may appear to conflict with either DQ7 or DQ6. In order to prevent such spurious
rejection, when an erroneous result occurs, the software routine should include an additional
two times loop to read the accessed location. If both reads are valid, then the device has
completed the write cycle, otherwise the rejection is valid.
Chip Erase
The EM39LV088 provides Chip-Erase feature, which allows the entire memory array to be
erased to logic “1” state. The Chip-Erase operation is initiated by executing a six-byte
command sequence with Chip-Erase command (10H) at address AAAH in the last byte
sequence. The Erase operation begins with the rising edge of the sixth WE# or CE#,
whichever occurs first. During the Erase operation, the only valid reads are Toggle Bit and
Data# Polling. See Table 3 for the command sequence, Figure 6 for timing diagram, and
Figure 15 for the flowchart. Any commands issued during the Chip-Erase operation are
ignored.
This specification is subject to change without further notice. (04.09.2004 V1.0)

EM39LV088
8M Bits (1Mx8) Flash Memory
SPECIFICATION
Sector/Block Erase
The EM39LV088 offers both Sector-Erase and Block-Erase modes. The Sector- (or Block-)
Erase operation allows the system to erase the device on a sector-by-sector (or
block-by-block) basis. The sector architecture is based on uniform sector size of 4 KByte.
The Block architecture is based on uniform block size of 64 KByte. The Sector-Erase
operation is initiated by executing a six-byte command sequence with Sector-Erase command
(30H) and sector address (SA) in the last bus cycle. The Block-Erase operation is initiated by
executing a six-byte command sequence with Block-Erase command (50H) and block
address (BA) in the last bus cycle. The sector or block address is latched on the falling edge
of the sixth WE# pulse, while the command (30H or 50H) is latched on the rising edge of the
sixth WE# pulse. The internal Erase operation begins after the sixth WE# pulse. The
End-of-Erase operation can be determined by using either Data# Polling or Toggle Bit
method. See Figures 7 and 8 for timing waveforms. Any commands issued during the
Sector or Block Erase operation are ignored.
Data# Polling (DQ7)
When the EM39LV088 is in the internal Program operation, any attempt to read DQ7 will
produce the complement of the true data. Once the Program operation is completed, DQ7
will produce the true data. Note that even though DQ7 may have valid data immediately
following the completion of an internal Program operation, the remaining data outputs may still
be invalid (valid data on the entire data bus will appear in subsequent successive Read cycles
after an interval of 1 µs). During internal Erase operation, any attempt to read DQ7 will
produce a “0”. Once the internal Erase operation is completed, DQ7 will produce a “1”. The
Data# Polling is valid after the rising edge of fourth WE# (or CE#) pulse for Program operation.
For Sector-Erase, Block-Erase, or Chip-Erase, the Data# Polling is valid after the rising edge
of sixth WE# (or CE#) pulse. See Figure 4 for Data# Polling timing diagram and Figure 13
for a flowchart.
Toggle Bit (DQ6)
During the internal Program or Erase operation, any consecutive attempts to read DQ6 will
produce alternating 1s and 0s, i.e., toggling between 1 and 0. When the internal Program or
Erase operation is completed, the DQ6 bit will stop toggling. The device is then ready for the
next operation. The Toggle Bit is valid after the rising edge of fourth WE# (or CE#) pulse for
Program operation. For Sector-Erase, Block-Erase or Chip-Erase, the Toggle Bit is valid
after the rising edge of sixth WE# (or CE#) pulse. See Figure 5 for Toggle Bit timing diagram
and Figure 13 for a flowchart.
Data Protection
The EM39LV088 provides both hardware and software features to protect the data from
inadvertent write.
This specification is subject to change without further notice. (04.09.2004 V1.0)

EM39LV088
8M Bits (1Mx8) Flash Memory
SPECIFICATION
Hardware Data Protection
Noise/Glitch Protection:
VDD Power Up/Down Detection:
Write Inhibit Mode:
A WE# or CE# pulse of less than 5 ns will not initiate a
write cycle.
The Write operation is inhibited when VDD is less than
1.5V.
Forcing OE# Low, CE# High, or WE# High will inhibit the
Write operation. This prevents inadvertent write during
power-up or power-down.
Software Data Protection (SDP)
The EM39LV088 provides the JEDEC approved Software Data Protection (SDP) scheme for
Program and Erase operations. Any Program operation requires the inclusion of the
three-byte sequence. The three-byte load sequence is used to initiate the Program
operation, providing optimal protection from inadvertent Write operations, especially during
the system power-up or power-down transition. Any Erase operation requires the inclusion of
six-byte sequence. See Table 3 for the specific software command codes. During SDP
command sequence, invalid commands will abort the device to Read mode within TRC. The
contents of DQ7-DQ0 can be VIL or VIH, but no other value, during any SDP command
sequence.
